Right, but that doesn't solve one of the main goals here: being able to
do private lookups on addresses that aren't in the main directory.

(I don't actually care much about being able to do path selection by
country. But I do want to make sure that whatever design I pick here
doesn't preclude doing that later.)

Compression (nearly) does this for free. Certainly enough that I don't
want to get messy with it. :)
